It is to be observed that Ithe Vouter ends ,ol. thestuds or truiinions 9 abut the Hat {outer vvalls ,of the notches 3, such walls being accurately finished to constitute thrust surfaces, v liile the aforesaid ends of the trannions areso.

In so fait as We are `advised, all joints heretofore constructed have relied upon shoulders at the inner ends of the trunnions to prevent endwise shifting of the latter but we deem our construction of great advantage over this, since it is' a diilicult task to accurately grind the-shoulders, whereas the flat outer ends of the-trunnionsinlay be easily our improved construction, thewashcrs lil will not' .be compressed as s.thelcaseI with numerous' other joints, since the lateral tlirustof the shaft sections. islnot-exerted described-such details liutoliviousl l numeriV ouselianges ina-yllieinade withiiiltlie scope-of the invention as' claimed without sacrificing any of the advantages thereof, i of |the bearing blocks-'.andfto close;.tlieg,openr, v
